“The science is clear. We have a consensus.” i.e. They don’t have a clue.
They will have to set up a complex multi-variable model with synthetic inputs and change all factors several times based on new theories before they can claim the science is”settled”.
Actually, seismology is fairly good physics. Unfortunately, the deeper earth is unavailable to direct sampling, so the best one can do is derive statistical models based on reflections and refractions of the interior.
Sometimes they work, sometimes they don’t.
